MI 3152 EurotestXC is an instrument from the new generation of Metrel’s multifunctional measuring instruments. The already well known functions like complete installation safety testing according to IEC/EN 61557 and AUTO SEQUENCE testing of TN, TT and IT earthing systems are managed by a completely new user interface based on large colour touch screen display. A wide range of functions is included: from on-line voltage monitoring, phase sequence testing, earth resistance measurement, illuminance measurement and TRMS current measurement up to RCD tests, line and loop impedance tests, earth resistance measurements as well as ISFL measurements and the IMD tests.

Built-in help screens for referencing on site.

Built-in fuse tables for automatic evaluation of the line / loop impedance result.

The Metrel Electrical Safety Manager is a common application for management of wide palette of Metrel’s electrical safety testers, portable appliance testers, machine testers and industrial safety testers. This application has a unified user interface with the new generation of Metrel’s instruments - same view same meaning. It enables the pretreatment for the measurements, viewing and editing of the measurement results and generation of professional reports. Depending on the instrument model or type the user can create AUTOSEQUENCEs, custom tests or single tests. They can be integrated into the custom created test structures and then uploaded into the measurement instrument.
